OMM-0145_D • GF-218 • 11/2/2020 Technical Support • (800) 526-0288 • Mon-Fri, 8 am - 5 pm EST Page 27 of 213
Specifies the time that this action advances the output; it
responds to the rate of change of the setpoint error (0.00 to
2.00 min.).
These three parameters eliminate Temperature
Overshoots during the “Warmup” period of a cold ignition
cycle by temporarily modifying the PID Gain parameter
during warmup.
Choose Yes to reset all parameters to the factory default.
Main Menu → Advanced Setup → Performance → Temperature Control → Temperature Conformance
These two settings create an “outlet temperature zone”
(between Active Setpoint + Deadband High and Active
Setpoint – Deadband Low) in which no Valve Position
corrections are attempted. (0 to 25°F for both)
The unit’s maximum allowable working temperature. If the
unit reaches this limit, it will fault and shut down (40 to 210
°F).
Main Menu → Advanced Setup → Performance → Temperature Control → Setpoint Range
Determines the upper and lower limit within which the
setpoint can vary.
Enables/disables Setpoint Limiting functionality.
Sets the number of °F below Setpoint High Limit the
unit’s outlet temperature must fall before the unit restarts (0
to 10°F, Setpoint Limiting = Enable).
Enables/disables Setback Schedule functionality
The Setpoint that will be in effect during the Setback
period. (60°F to 245°F, Setback Schedule = Enabled).
The Setback period’s start time (Setback Schedule =
Enable).
The Setback period’s end time (Setback Schedule =
Enable).
Main Menu → Advanced Setup → Performance → Temperature Control → FFWD Settings
Displays the current FFWD temperature.
Displays the calculated PID output.
Displays the current FFWD output.
Adjusts the output by adding an offset to the breakpoint
chart at minimum flow. This is used to fine tune Feed-
Forward (FFWD) output at low flow levels. (-50 - +50°F)
Adjusts the output by changing the scaling of the
breakpoint chart at maximum flow. (-50 - +50°F)
Enables Outlet Feedback functionality.
The percentage of feedback from the water outlet sensor
the algorithm factors to determine fire rate (0.01 – 1.00).
The Feedback start position (0 – 100%).
The Feedback end position (0 – 100%).
Specifies the maximum Feedback position (0 – 100%).
Displays the current feedback value.
Breakpt at 100 to
Breakpt at 0
Allows breakpoint temperature settings to be entered for
100% to 0% in 10% increments (60 – 260°F).
Enables temperature governor limiting functionality, which
aggressively reduces the effective Fire Rate as the Outlet
Temperature approaches the High Temperature Limit.
